概括
面包发酵和时间显著改变B组三甲的含量,影响其生物可访问性和吸收性. 单独对最终产品进行测试不足以确定实际的甲暴露风险.
科学领域:
- 食品化学 食品化学
- 菌类毒理学 菌类毒理学
- 食品安全 食品安全
背景情况:
- B组的三甲基是谷物食品如面包中发现的真菌毒素.
- 它们的形式可以在食品加工和消化过程中相互转换,使暴露评估复杂化.
研究的目的:
- 调查发酵和制参数对面包中B组三可铁的生物可访问性和透性的影响.
- 为了了解三合体在制造面包和模拟消化过程中的转化.
主要方法:
- 面包是用不同的第一次发酵,第二次发酵和时间准备的.
- 使用了模拟胃和肠道阶段的体外消化模型.
- 量化了特定的三合甲基 (尼瓦伦醇,脱氧尼瓦伦醇,乙化衍生物和葡萄糖类) 的生物可访问性和透性.
主要成果:
- 较长的 (120分钟) 减少了尼瓦伦醇 (NIV),15-乙-脱氧尼瓦伦醇 (15-AcDON) 和脱氧尼瓦伦醇-3-葡萄糖化物 (DON-3G);较短的 (30分钟) 增加了NIV.
- 在胃阶段,脱氧尼瓦伦醇 (DON) 和3-乙-脱氧尼瓦伦醇 (3-AcDON) 的生物可访问性增加,而DON-3G和15-AcDON无法检测到.
- 在肠道阶段,DON-3G被检测到,但NIV没有. 观察到DON (100%) 和DON-3G (91%) 的高透率.
结论:
- 面包加工参数显著影响B组三菌的命运和生物可用性.
- 在制造面包和消化过程中,三可烯形式的相互转换突显了暴露评估的复杂性.
- 仅仅评估最终产品的污染物含量不足以准确评估甲暴露的风险.

Fungal Group Zygomycota
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
